You get 2 circles of diameter. If you were trying to find a perimeter, Never double the diameter. If you have a radius, You have to double it to get a perimeter.
If you double the circumference. the diameter like wise would double.
As circumference = π x diameter and π is constant (≈ 3.14159), doubling the diameter will double the circumference.
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
It'll more than likely double the circumference, too. BOOM.
As the area of a circle A equals pi times the radius squared, and doubling the diameter means multiplying the radius by four, the area is multiplied by 16 when you double the diameter.
Nothing happens. A person sitting next to you won't know that you did anything to your circle. But you'll have a bigger circle. The radius will be double the originasl radius. The circumference will be double the original circumference. The area will be four times the original area.
The diameter is double the radius of a circle. So you get 5 inches for the diameter.
I would think it would double also. Say Circle A has a diameter of 1 inch and Circle B has a diameter of 2 inches. To get the circumference, you multiply the diameter by pi (3.14). So 1 x 3.14 = 3.14 so that is the circumference of Circle A. To get the circumference of Circle B you need to multiply 2 x 3.14 = 6.28. And 6.28 is twice 3.14 so I would think the circumference doubles.
it is the length of a circle from left to right you basically double the radius which is half of the diameter.
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
The circumference of a circle divided by its diameter is equal to the value of pi
Diameter = double the radius = 16
